AUTOMOBILE SHIFT-LEVER LOOK.

Application filed February 13, 1924.

To all whom it may cancer/n:

Be it known that I, HUGI-I F. MoDoNALD, a citizen of the United States,and a resident of the city and county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inAutomobile Shift-Lever Locks, of which the following is a specification.

The present invention relates to improvements in automobile shift-leverlooks, and has for a principal object the provision of a simple meansfor looking and preventing the operation of automobiles by unauthorizedpersons.

The invention comprises elements and certain improvements andcombinations of parts adapted to engage andlock against movement theshift-levers of automobiles thereby preventing a controlled operation ofthe machine.

In the accompanying drawings,I forming a part of this specioation, andin which similar characters of reference refer to like parts,throughout, Figure 1 is a plan view of my invention showing it assecured to the front of an automobiles seat and in locked position aboutthe shift-lever, thed'otted-in Serial No. 692,487.

cessed lock 6 and a pivotally attached arm 8 fashioned to embrace, inconnection with 40 said seat, a shift-lever 12 and enter into lockedengagement with the bolt 10, through its hasp-like extremity 9, uponbeing brought nto looking relationship with said shiftever.

Normally when out of service, the device may be made to occupy arecessed position in the seatls front, not shown, from which it is swungto encircle the shift-lever, automatically looking itself thereabout andfrom which a key is necessary for its release, after which, it may bereturned to its recess.

Having thus described my invention, I claim, and desire to secure byLetters Patent:

In an automobile shift-lever lock, the combination, with anautomobile-body section and a shift-lever, of a bracket rigidly securedto said body section, a hinged member borne by said bracket andcomprising a channeled bar having a seat at its free end adapted toreceive and seat said shift-lever, an arm pivotally attached to the endof said channeled bar and having a rearwardly eX- tending section endingin a hasp, said arm being fashioned to embrace the shift-lever, inconnection with the said shift-lever seat of the channeled bar, the saidchanneled bar being provided with a recessed lock having a spring boltadapted to engage said hasp, said lock being so positioned between theflanges of the channeled bar as to be flush, when in locked position,with the outer edges of said fianges and fully protected and securedagainst tampering therewith.
